sendmail issue

Hi,

yesterday I had issues, sendmail was not responding quickly while sending email and users did not receive any email,

This happened with sendmail on solaris 10 and also with sendmail on a linux box.

Found it is something to do with DNS blacklists,

following lists did not work for me,

Quote:
on linux :
sbl-xbl.spamhaus.org , pbl.spamhaus.org
on solaris :
unconfirmed.dssbl.org, list.dnsbl.org, dul.dnsbl.sorbs.net, zen.spamhaus.org
now this could be a known issue, but why so many blacklists servers stopped suddenly Smilie

Again, is there any solution on this , like some config we can do in sendmail to work around.

I have removed the lists not responding to nslookup but the ones which are already here could also stop responding some day Smilie

by mentioning the blacklists here, I hope it helps others also SmilieSmilie

Thanks!

Did you perform any patching activity to the servers?
